This invention relates to 'suction rolls for paper machines. j Y

An important obj ect of the invention is the provision of`a simple andeffective means for maintaining the suction box of ,such rolls in anydesired position within the roll.

I A further object of the invention is to provide a means for readilyadjusting the box which serves to lock the box in its adjusted positionsin the roll.

A still further object ofthe invention is to provide in a structure ofthis character an arrangement such that the position of the box withinthe shell may be determined at any time.

A still further and more specific object of the invention is theprovision of a construction enabling the heavy side of the suction boxto be turned to the bottom so that the box will' be supported andbalanced during dismantling operations.A

These and other lobjects I attain by the con struction shown in theaccompanying drawings wherein, for thepurposeo'f illustration, I haveshown a preferred embodiment of my invention and wherein: l

lFig. 1 is a longitudinal sectional view through a suction roll equippedwith suction box adjusting means constructed in accordance with myinvention; Fig. 2 is a side elevation thereof; and

Fig. S-is a section on line 3 3 of Fig. l,

portions of the end head of thel shelllbeing broken away to illustratethe position ofthe paekings of the suction box with relation to theindicator.

.Referring now more particularly to the drawings, the numeral 10generally designates the perforated shell of a suctionl roll and 11ahead attached to the roll and' having projecting therefrom a hollowjournal 12 mounted in a bearing 13" and rotated through a suitabledriving means.

Arranged within the shell 10 is a suction box-.14 having a head 15-equipped with a project-ing tubular extension 16 directed through thejournal -of the sh-ell. Exteriorly to the journal the outer end ofthetubular extension 16 is equipped with an exhaust header 17 which througha quick'detachable iange 21 through a loose block 23 which may beremoved to enable the felts or wires of the machine to be changed. Tothis block I secure a bracket24 affording bearings 25 for a worm 26which meshes with worm gear 20.

It will be obvious that by rotating worm 26, which is equipped with alwreneh-receivf ing shank 27 to permit rotation, the tubular extension 16and through this extension the suction box`14 will be rotated to placethe suction box in a desired adjusted position. To assist in thisadjustment the face of the gear 20 is equipped with indicator marks 28aligning with the inner faces of the packings of the suction box and bynoting the position of these indicator marks a desired adjusted.position of the box may be obtained without the necessity of removingthe felts or wires to permit the inspection of the roll. When it isdesired to dismantle the roll the box 14 through worm 26 may bel rotateduntil these .packings are disposed at the lower end of the shell s othat the box will besupported from the shell-walland will not beinclined to suddenly rotate when released.

.While I have disclosed the box adjustment l asvsecured to a tubularextension'whieh communicates with a header, .it will of course,beunderstood that this arrangement can be modified and the adjustmentdisposed at either endof the roll simply by extending the head journalof the box ',suiciently to enable application of the gear 20 thereto.This arrangement may be applied with equal facility to either a director non-direct driven roll and may be placed at either end of the vrollas is found necessary or desirable. It

will be noted that the construction provided allows not only adjustmentof the suction box but also provides for complete rotation thereof ifdesired. Such complete rotation is un necessary, but rotation through atleast 180 'should be provided. j

Since the construction is capable of a considerable range of change andmodification,

I do not Wish to be understood as limiting myself to the specificarrangement herein disclosed except as hereinafter claimed.

I claim:

1. In a suction roll, a support, a bearing above and in spaced relationto the support, a perforated shell having a tubular journal engaged insaid bearing, a suction box Within the shell and having an extensionprojecting through said journal at the outer end thereof, a removableblock supporting said bearing from the support and means supported fromsaid removable block operatively engaging said extension to rotate thesame from which the extension is disengageable by a vertical movement.

2. In a suction roll, a support, a bearing above and in spaced relationto the support` a perforated shell having a tubular journal. engaged insaid bearing, .a suction boX within the shell and having an extensionprojecting through said j ournal at the outer end thereof, a removableblock supporting said bearing from thevsupport and means supported fromsaid removable block operatively engaging said extension to rotate thesame from which the extension is disengageable by a vertical movement,said rotating means having engagementwith said extension locking thesame in adjusted positions.

3. In a suction roll, asupport, a bearing above and in spaced relationtothe support, a perforated shell having a tubular journal engaged insaid bearing, a suction boX Within the shell and having an extensionprojecting through said journal at the outer end thereof, a removableblock supporting said bearing from the support, a bracket projectingfrom said block, a horizontal Worm rotatably supported by the bracketand a Worm gear secured to the extension of the suction box and engagedwith said worm.
